Is a heat pump worth it in Arlington Heights?
Here in Arlington Heights, the honest answer is that a heat pump raises your annual running cost. Swap a failed furnace and AC for a heat pump rather than buying like-for-like, and the extra cost here runs $3,500 after a $2,000 federal tax credit. Running costs here land $228 a year HIGHER than the furnace it replaces, so that premium is never recovered. That's Arlington Heights's own climate and rates talking, not a hedge or a caveat.
How cold Arlington Heights actually gets
4991 heating degree days pile up here every year, so Arlington Heights has a real but manageable winter; the cooling side runs to 1020 cooling degree days, where summers are hot enough that cooling matters as much as heating. Sizing runs off the design temperature, not the average day: -0.9°F here (record low -11°F), which works out to a seasonal COP of 2.68 for the cold-climate class of unit this climate calls for. A cold-climate unit is the right call in Arlington Heights — below 25°F design temperature, a standard heat pump leans hard on electric-resistance backup, which erases most of the savings.

Arlington Heights's running-cost comparison, in dollars
A 2000-square-foot house here would pull roughly 4,716 heating kilowatt-hours annually on top of cooling, totalling about $1,065 a year on electricity. Arlington Heights's gas rate of 11.25 per Mcf, applied to the 52 Mcf a year the furnace burns, puts its running cost near $837 a year, against 19.06¢ per kWh for electricity. Priced as a standalone purchase rather than against a like-for-like replacement, equipment payback runs past the 15-year equipment life, for a 15-year net position $6,917 behind.
The other scenario: no gas furnace to begin with
Not every home in Arlington Heights has gas service. Swap the comparison to resistance heat instead of gas, and Arlington Heights's answer improves. The saving here runs about $1,596 a year, which recovers the extra $8,000 spent going electric in roughly 5 years.
How Arlington Heights compares nationally
Among 3206 cities, Arlington Heights's winter puts it at rank 711 for severity, while its size puts it at rank 508 for population — 1 in both cases being the extreme. That's the coldest third of the dataset, where climate does most of the work behind this figure.
